More specifically, we provide characterizations of these concepts in terms of the intuitionistic fuzzy lattice meet and join operations, in terms of some associated fuzzy sets, as well as, in terms of their crisp level sets. Furthermore, we introduce the concepts of prime intuitionistic fuzzy ideals (resp. filters) as interesting kinds, and investigate their various properties and characterizations. 2025 80 100 3423 https://creativecommons.org/licenses/by/4.0/ 10.54216/IJNS.250408 https://www.americaspg.com/journal/21/article/3423 https://www.americaspg.com/storage/91735275426.pdf
